Voith connection couplings provide a backlash-free, frictional, quick-setting/releasing shaft-hub connection. The setting or releasing occurs hydraulically. Depending on the application, various operating principles are available, all of which offer the advantage of a backlash-free pressure connection.
• Mechanical shaft-shaft/shaft-flange connection
• Hydraulically set and released• No oil pressure required for transmitting
torque
The inner and outer tapered sleeves are hydrau-lically pushed towards each other to create a ra-dial force. Subsequently, a frictional connection is created between shaft, coupling and shaft/flange.
During setting and releasing, the shaft hub re-mains static, only the tapered outer sleeve is moved.

• Hydraulic hollow sleeve-shaft-hub connection• Pumped up hydraulically• Oil pressure is required for transmitting torque
The frictional connection between the shaft, cou-pling and hub is created by hydraulic expansion of the coupling unit. The hydraulic pressure crea-tes a radial force within the coupling.

The coupling friction surfaces are treated with a unique pro-cess, which more than doubles the friction factor. This gives the corresponding increase of the transmittable torque.
Our surface treatment gives HyCon, HyGrip and HyLoc the most compact and effective connection coupling available on the market.
A thin fatigue- and wear-resistant layer of tungsten carbide coating can be applied onto the inner surface of the coup-ling. The high friction coating (HFC) strengthens the bond between the shaft and sleeve, which more than doubles the torque capacity.
HFC is standard on all HyCon and optional on HyGrip and HyLoc.
High friction coatingdoubles the torque capacity
• Mechanical shaft-hub connection• Hydraulically set and released• Oil pressure is not required for transmitting
torque
By hydraulically pushing a tapered sleeve inside a coupling unit, a radial force is created. Subse-quently, a frictional connection is created bet-ween shaft, coupling and hub.
During setting and releasing, the shafthub remains static, only the tapered conical sleeve inside the coupling moves.

DNV GL approved HyCon connection couplings ensure a re-liable low-weight friction connection with outstanding perfor-mance and torque capacity. HyCon is easily installed without oil leakage and is safe both for people and environment. With an increased payload capacity due to at least 40% reduced system weight*, the installation, setting and releasing is fast, easy and secure.
OperationThe HyCon connection coupling consists mainly of a tapered parts sleeve and a tapered hub. To secure the shaft, the tape-red hub is hydraulically pushed up onto the tapered sleeve. The pressure assembly creates a tight grip that holds the shaft. When the coupling is pressurized, the tapered surfaces are totally separated from each other. The seals on both sides of the coupling ensure that no oil leak can occur. This smart design minimizes the environmental impact.
*compared to conventional connection couplings without HFC.

The HyGrip connection coupling consists of a twin-walled pressure sleeve. It is pressurized with oil up to 1000 bar and sealed with a brass valve. This results in a completely backlash-free frictional connection. HyGrip connection couplings can be specifically designed to meet the exact requirements of the application. The torque transmission capacity and the axial forces are proportional to the oil pressure. The connection can be set and released very quickly if a suitable hydraulic pump is used. HyGrip couplings have limited radial force capacity.
Customer benefits:
+ Improved control of processes + Increased service life of all driveline components
+ No notch effects as the keyways are eliminated
+ Rapid and accurate installation + Improved control of actual process
+ Able to withstand dirty and difficult environments
+ Extremely high torque capacity
Design features:
• Backlash-free connection• Design optimized for simple
assembly and disassembly• Minimized radial and axial run out• Robust design• High friction coating (HFC)
optional

The HyLoc connection coupling consists of a hollow sleeve, where the internal chamber is a conical ring piston that is moved hydraulically. The ensuring radial expansion produces a backlash-free connection between a shaft and a hub. The pressure required for assembly is normally 1000 bar. A maximum of 1200 bar is usually required for disassembly. After assembly, the oil is drained so that there is no residual oil pressure in the coupling during operation. The same applies for dis-assembly. The ring piston is provided with specially arranged lubrication grooves, hence a lubricating film is created when the ring piston moves between the working surfaces.
HyLoc connection coupling for extreme radial forces
Customer benefits:
+ Improved control of processes + Increased service life of all driveline components
+ No notch effects as the keyways are eliminated
+ Rapid and accurate installation + Improved control of actual process
+ Ideally suited for roll connections + Able to withstand dirty and difficult environments
+ Extremely high torque capacity + High radial force capacity
Design features:
• Backlash-free connection• Design optimized for simple
assembly and disassembly• Minimized radial and axial run out• Design optimized for withstanding
high radial forces• Robust design• High friction coating (HFC)
